Scientz SCIENTZ-30F/A Pilot-Scale In-Situ Shelf Freeze Dryer with Silicone Oil Heating

Overview

The Scientz SCIENTZ-30F/A is a pilot-scale, in-situ shelf freeze dryer engineered for precise process development and small-batch lyophilization of thermolabile and biologically active materials. It operates on the principle of sublimation under deep vacuum—where frozen water transitions directly from solid to vapor without passing through the liquid phase—thereby preserving structural integrity, biological activity, and chemical stability of sensitive samples such as pharmaceuticals, microbial cultures, proteins, vaccines, nucleic acids, and botanical extracts. Unlike conventional air-cooled or electrically heated systems, the SCIENTZ-30F/A employs a silicone oil circulation heating system integrated with a dual-stage cascade refrigeration unit, enabling accurate, uniform, and programmable temperature control across all shelves. This architecture supports rigorous process parameter optimization—including ramp rate, hold duration, and pressure modulation—making it suitable for both research-driven formulation studies and GMP-aligned pilot manufacturing.

Key Features

• Shelf-based in-situ freezing and drying: Eliminates sample transfer between pre-freezing and lyophilization steps, reducing contamination risk and preserving morphology.
• Silicone oil heating system: Delivers ±1 °C shelf temperature uniformity (RA ≤ 0.5 µm surface finish), superior thermal stability, and reproducible heating/cooling profiles compared to resistive heating.
• Cascade refrigeration: Achieves cold trap temperatures ≤−70 °C (no load); optional configuration extends to ≤−80 °C using imported compressors for enhanced ice capture efficiency.
• Industrial-grade PLC controller with 7-inch color touchscreen: Supports manual/auto operation modes, real-time monitoring of shelf temperature, product temperature (via optional Pt100 probes), vacuum level, and cold trap temperature.
• Data integrity & compliance: Stores up to 40 customizable freeze-drying protocols (40 segments each), automatic logging of all critical parameters, audit-trail-capable data export via USB, and multi-level user access control aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations.
• Robust vacuum system: Custom-engineered corrosion-resistant vacuum pump (optional oil mist filter and automatic differential-pressure valve to prevent backstreaming).
• Double-chamber design: Corrosion-resistant stainless steel cold trap with external coil geometry for easy cleaning; transparent aerospace-grade acrylic door for visual process monitoring.

Sample Compatibility & Compliance

The SCIENTZ-30F/A accommodates diverse primary containers including vials (2–50 mL), serum bottles, Petri dishes, and custom trays—compatible with both standard and stopper-pressing configurations. Its controlled shelf temperature range (−50 °C to +80 °C) and adjustable vacuum setpoints (0.1–50 Pa) support lyophilization of aqueous, organic-aqueous, and high-viscosity formulations. The system meets ISO 22000 and ISO 13485 design principles for food and medical device applications and is routinely deployed in laboratories adhering to GLP, GMP, and USP guidelines. Optional co-located coagulation point measurement and nitrogen backfill interface further enable full-cycle process validation per ICH Q5C and Q8(R2).

Software & Data Management

The embedded control software provides full cycle automation with three built-in ramp modes: linear heating, slope-controlled ramping, and temperature-hold timing. All operational events—including power interruptions—are timestamped and retained in non-volatile memory. Data files (CSV format) include time-stamped shelf temperature, chamber pressure, condenser temperature, and user-defined annotations. U盘-exported logs are compatible with common LIMS platforms and statistical process control tools (e.g., JMP, Minitab). Remote supervision is supported via optional Ethernet/WiFi module and mobile application (iOS/Android), enabling secure off-site monitoring without compromising network isolation requirements.

Applications

This freeze dryer serves cross-disciplinary workflows across academia, regulatory labs, and biopharmaceutical R&D. Typical use cases include: optimization of lyophilization cycles for monoclonal antibodies and mRNA-LNPs; stabilization of probiotics and bacteriophages; preparation of reference standards for environmental soil/sludge analysis; dehydration of plant tissue for metabolomic profiling; archival preservation of historical manuscripts and biological specimens; and scale-up trials for oral disintegrating tablets and ophthalmic biologics. Its 0.32 m² shelf area and 6 kg/24 h ice capacity bridge the gap between benchtop development and early commercial production—particularly valuable for contract development and manufacturing organizations (CDMOs) conducting tech transfer activities.

FAQ

What is the maximum batch size this unit can handle?

Based on a typical loading density of 10–15 mL per vial and full shelf utilization, the SCIENTZ-30F/A supports batches of approximately 2,000–3,000 standard 10-mL vials per cycle.

Does the system support PAT integration?

Yes—optional analog/digital I/O ports allow connection to external sensors (e.g., tunable diode laser moisture analyzers, NIR probes) for real-time critical quality attribute (CQA) monitoring.

Is the cold trap condenser accessible for routine maintenance?

Yes—the external coil design permits rapid defrosting and wipe-down cleaning without disassembly; no internal gaskets or blind zones hinder accessibility.

Can the unit operate unattended overnight?

Absolutely—the system includes auto-restart after power recovery, continuous data logging, and configurable alarms (e.g., over-temperature, vacuum loss, door open), making it suitable for extended autonomous runs.

What regulatory documentation is provided with purchase?

Each unit ships with Factory Acceptance Test (FAT) report, IQ/OQ templates compliant with ASTM E2500, and a complete set of electrical schematics, piping & instrumentation diagrams (P&IDs), and material certifications (316L SS, FDA-compliant elastomers).
